SAGITTAL STABILITY OF THE KNEE JOINT AFTER TOTAL ARTHROPLASTY USING A COMPUTER NAVIGATION SYSTEM

Abstract

The article provides a comparative analysis of the functional results of total knee arthroplasty and knee postoperative stability in the Sagittal plane in 124 patients (22 men and 102 women) suffering from gonarthrosis, aged 51 to 83 years (average 69.8 years), operated on with using a standard technique (n = 62) or using a computer navigation system (n = 62), observed for 6 to 36 months. from the time of surgery. The use of the navigation system made it possible in some cases to perform more accurate resection in the sagittal plane of the femur and tibia (9,6% of cases of deviations from the sagittal plane versus 25,8 % in the control group), as well as to achieve the optimal range of motion after arthroplasty: 124,8±1,7 versus 127±4,7 (p < 0.05).
